War wagon

The Dongwu Che (Chinese: 洞屋车) "war wagon" was a mobile armored cart used in Ancient China from the 5th century BC. It was used for the purpose of protecting warriors on the battlefield. The Chinese war wagon was a kind of mobile protective cart with a shed-like roof. It would serve to be rolled up to city fortifications to provide protection for sappers digging underneath to weaken a walls foundation. Other versions were later used as wagon trains to protect against cavalry charges and arrows during the Han Dynasty's campaigns against the Xiongnu steppe nomads. The early Chinese war wagon became the basis of technologies for the making of ancient Chinese south-pointing chariots.[1][2] A medieval European war wagon was developed by the Hussite Wars around 1420 by Hussite forces rebelling in Bohemia.[3]

It was a heavy wagon given protective sides with firing slits and heavy firepower from either a cannon or a force of hand-gunners, archers and crossbowmen, supported by infantry using spears, pikes and flails. Groups of them could form defensive works, but they also were used as hardpoints for formations or as firepower in pincer movements.[4] This early use of gunpowder and innovative tactics helped a largely peasant infantry stave off attacks by the Holy Roman Empire larger forces of mounted knights.

After the Hussite wars, they stayed in usage as the special tactical weapon of Bohemian mercenaries which prevailed against knights or foot soldiers. Its successful history came to an end, at least for large scale engagements, with the development of field-piece artillery: a battle wagon wall "fortress" of approximately 300 wagons was broken at the Battle of Wenzenbach September 12, 1504 by the culverines (early canons) and muskets of the landsknecht regiment of G. Frundsberg.

Hussites
–
This predominantly religious movement was propelled by social issues and strengthened Czech national awareness. Among present-day Christians, Hussite traditions are represented in the Moravian Church, Unity of the Brethren, the arrest of Hus in 1414 caused considerable resentment in Czech lands. The authorities of both countries appealed urgently and repeatedly to King Sigismund to release Jan Hus, when news of his death at the Council of Constance in 1415 arrived, disturbances broke out, directed primarily against the clergy and especially against the monks. Even the Archbishop narrowly escaped from the effects of popular anger. The treatment of Hus was felt to be a disgrace inflicted upon the whole country, King Wenceslaus, prompted by his grudge against Sigismund, at first gave free vent to his indignation at the course of events in Constance. His wife openly favoured the friends of Hus, avowed Hussites stood at the head of the government. The university would arbitrate any disputed points, the entire Hussite nobility joined the league. Other than verbal protest of the treatment of Hus, there was little evidence of any actions taken by the nobility until 1417. The chalice of wine became the central identifying symbol of the Hussite movement, the prospect of a civil war began to emerge. Pope Martin V as Cardinal Otto of Colonna had attacked Hus with relentless severity and he energetically resumed the battle against Huss teaching after the enactments of the Council of Constance. He wished to completely the doctrine of Hus, for which purpose the co-operation of King Wenceslaus had to be obtained. In 1418, Sigismund succeeded in winning his brother over to the standpoint of the council by pointing out the inevitability of a war if the heretics in Bohemia found further protection. Hussite statesmen and army leaders had to leave the country and Roman Catholic priests were reinstated and these measures caused a general commotion which hastened the death of King Wenceslaus by a paralytic stroke in 1419. Hussism organised itself during the years 1415–1419, the moderate party, who followed Hus more closely, sought to conduct reform while leaving the whole hierarchical and liturgical order of the Church untouched. This required the removal of the hierarchy and the secularisation of ecclesiastical possessions. The radicals preached the sufficientia legis Christi—the divine law is the rule and canon for human society, not only in the church. But above all they clung to Wycliffes doctrine of the Lords Supper, denying transubstantiation, the radicals had their gathering-places all around the country. Their first armed assault fell on the town of Ústí, on the river Lužnice

Chinese language
–
Chinese is a group of related, but in many cases mutually unintelligible, language varieties, forming a branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many ethnic groups in China. Nearly 1.2 billion people speak some form of Chinese as their first language, the varieties of Chinese are usually described by native speakers as dialects of a single Chinese language, but linguists note that they are as diverse as a language family. The internal diversity of Chinese has been likened to that of the Romance languages, There are between 7 and 13 main regional groups of Chinese, of which the most spoken by far is Mandarin, followed by Wu, Min, and Yue. Most of these groups are mutually unintelligible, although some, like Xiang and certain Southwest Mandarin dialects, may share common terms, all varieties of Chinese are tonal and analytic. Standard Chinese is a form of spoken Chinese based on the Beijing dialect of Mandarin. It is the language of China and Taiwan, as well as one of four official languages of Singapore. It is one of the six languages of the United Nations. The written form of the language, based on the logograms known as Chinese characters, is shared by literate speakers of otherwise unintelligible dialects. Of the other varieties of Chinese, Cantonese is the spoken language and official in Hong Kong and Macau. It is also influential in Guangdong province and much of Guangxi, dialects of Southern Min, part of the Min group, are widely spoken in southern Fujian, with notable variants also spoken in neighboring Taiwan and in Southeast Asia. Hakka also has a diaspora in Taiwan and southeast Asia. Shanghainese and other Wu varieties are prominent in the lower Yangtze region of eastern China, Chinese can be traced back to a hypothetical Sino-Tibetan proto-language. The first written records appeared over 3,000 years ago during the Shang dynasty, as the language evolved over this period, the various local varieties became mutually unintelligible. In reaction, central governments have sought to promulgate a unified standard. Difficulties have included the great diversity of the languages, the lack of inflection in many of them, in addition, many of the smaller languages are spoken in mountainous areas that are difficult to reach, and are often also sensitive border zones. Without a secure reconstruction of proto-Sino-Tibetan, the structure of the family remains unclear. A top-level branching into Chinese and Tibeto-Burman languages is often assumed, the earliest examples of Chinese are divinatory inscriptions on oracle bones from around 1250 BCE in the late Shang dynasty

Sapper
–
They are also trained to serve as infantry personnel in defensive and offensive operations. A sappers duties are devoted to tasks involving facilitating movement, defence and survival of allied forces, the term sapper is used in the British Army and Commonwealth nations, Polish Army and the U. S. military. The phrase sapper comes from the French saper, saps were excavated by brigades of trained sappers or instructed troops. When an army was defending a fortress with cannon, they had an obvious height, the attacking armys artillery had to be brought forward, under fire, so as to facilitate effective counter-battery fire. This was achieved by digging what the French termed a sappe, using techniques developed and perfected by Vauban, the sappers began the trench at such an angle so as to avoid enemy fire enfilading the sappe. As they pressed forward, a position was prepared from which cannon could suppress the defenders on the bastions, the sappers would then change the course of their trench, zig-zagging toward the fortress wall. Each leg brought the attackers artillery closer until the cannon would be sufficiently suppressed for the attackers to breach the walls. Broadly speaking, sappers were experts at demolishing or otherwise overcoming or bypassing fortification systems. An additional term applied to sappers of the British Indian Army was miner, the native engineer corps were referred to as sappers and miners, as for example, the Royal Bombay Sappers and Miners. The term arose from a task done by sappers to further the battle after saps were dug, the saps permitted cannon to be brought into firing range of the besieged fort and its cannon, but often the cannon themselves were unable to breach the fort walls. This was dangerous work, often lethal to the sappers, and was resisted by the besieged enemy. Since the two tasks went hand in hand and were done by the troops, native Indian engineer corps came to be called sappers and miners. Sapper is the Royal Engineers equivalent of private, the term sapper was introduced in 1856 when the Corps of Royal Sappers and Miners was amalgamated with the officer corps of the Royal Engineers to form the Corps of Royal Engineers. During the Sinai and Palestine Campaign of World War I Australian sappers repaired a bridge at the crossing of the Jordan River at Jisr Benat Yakub. Here the retreating Ottoman and German rearguard had blown up the central arch which was repaired in five hours by sappers attached to the Australian Mounted Division. Australian Sappers in the Vietnam War were also honoured in the Cold Chisel song Khe Sanh with the line I left my heart to the Sappers round Khe Sanh, in the Canadian Forces, sappers exist both in the regular force and reserve force. The rank of sapper is used instead of private trained to signify completion of the Engineer DP1 course, Canadian sappers have been deployed in many major conflicts in recent history including World War I, World War II, the Korean War, and the War in Afghanistan. Ultimately, the objective of the sappers is to facilitate the living, moving, and fighting for friendly troops on the battlefield, the motto of the Canadian Military Engineers is Ubique a motto shared with the Royal Canadian Artillery

Han dynasty
–
The Han dynasty was the second imperial dynasty of China, preceded by the Qin dynasty and succeeded by the Three Kingdoms period. Spanning over four centuries, the Han period is considered an age in Chinese history. To this day, Chinas majority ethnic group refers to itself as the Han people and it was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods, the Western Han or Former Han and the Eastern Han or Later Han, the emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the gentry class. The Han Empire was divided into areas controlled by the central government using an innovation inherited from the Qin known as commanderies. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States, from the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1911 AD, the Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty. The coinage issued by the government mint in 119 BC remained the standard coinage of China until the Tang dynasty. The period saw a number of limited institutional innovations, the Xiongnu, a nomadic steppe confederation, defeated the Han in 200 BC and forced the Han to submit as a de facto inferior partner, but continued their raids on the Han borders. Emperor Wu of Han launched several campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries, the territories north of Hans borders were quickly overrun by the nomadic Xianbei confederation. Imperial authority was seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, following Liu Bangs victory in the Chu–Han Contention, the resulting Han dynasty was named after the Hanzhong fief. Chinas first imperial dynasty was the Qin dynasty, the Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huangdi. Within four years, the authority had collapsed in the face of rebellion. Although Xiang Yu proved to be a commander, Liu Bang defeated him at Battle of Gaixia. Liu Bang assumed the title emperor at the urging of his followers and is known posthumously as Emperor Gaozu, Changan was chosen as the new capital of the reunified empire under Han

Xiongnu
–
The Xiongnu, were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the leader after 209 BC. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and their relations with adjacent Chinese dynasties to the south east were complex, with repeated periods of conflict and intrigue, alternating with exchanges of tribute, trade, and marriage treaties. Attempts to identify the Xiongnu with later groups of the western Eurasian Steppe remain controversial, Scythians and Sarmatians were concurrently to the west. The identity of the core of Xiongnu has been a subject of varied hypotheses, because only a few words, mainly titles. The name Xiongnu may be cognate with that of the Huns and/or the Huna, other linguistic links – all of them also controversial – proposed by scholars include Iranian, Mongolic, Turkic, Uralic Yeniseian, or multi-ethnic. Ancient China often came in contact with the Xianyun and the Xirong nomadic peoples, in later Chinese historiography, some groups of these peoples were believed to be the possible progenitors of the Xiongnu people. These nomadic people often had repeated confrontations with the Shang and especially the Zhou. During the Warring States period, the armies from the Qin, Zhao, qins campaign against the Xiongnu expanded the Qin dynastys territory at the expense of the Xiongnu. In 215 BCE, Qin Shi Huang sent General Meng Tian to conquer the Xiongnu and drive them from the Ordos Loop, after the catastrophic defeat at the hands of General Meng Tian, the Xiongnu leader Touman was forced to flee far into the Mongolian Plateau. The Qin empire became a threat to the Xiongnu, which led to the reorganization of the many tribes into a confederacy. Chubei Huyan Lan Luandi Qiulin Suibu In 209 BCE, three years before the founding of Han China, the Xiongnu were brought together in a confederation under a new chanyu. This new political unity transformed them into a formidable state by enabling formation of larger armies. The Xiongnu adopted many of the Chinese agriculture techniques such as labor for heavy labor, wore silk like the Chinese. The reason for creating the confederation remains unclear, to the north he conquered a number of nomadic peoples, including the Dingling of southern Siberia. He crushed the power of the Donghu people of eastern Mongolia and Manchuria as well as the Yuezhi in the Hexi Corridor of Gansu, Modu also reoccupied all the lands previously taken by the Qin general Meng Tian. Under Modus leadership, the Xiongnu threatened the Han Dynasty, almost causing Emperor Gaozu, the first Han emperor, to lose his throne in 200 BCE. By the time of Modus death in 174 BCE, the Xiongnu had driven the Yuezhi from the Hexi Corridor, killing the Yuezhi king in the process and asserting their presence in the Western Regions

South-pointing chariot
–
The south-pointing chariot was an ancient Chinese two-wheeled vehicle that carried a movable pointer to indicate the south, no matter how the chariot turned. Usually, the pointer took the form of a doll or figure with an outstretched arm, the chariot was supposedly used as a compass for navigation, and may also have had other purposes. No ancient chariots still exist, but many extant ancient Chinese texts mention them, some include information about their inner components and workings. There were probably several types of south-pointing chariot which worked differently, in most or all of them, the rotating road wheels mechanically operated a geared mechanism to keep the pointer aimed correctly. The mechanism had no magnets and did not automatically detect which direction was south, the pointer was aimed southward by hand at the start of a journey. Thus the mechanism did a kind of dead reckoning, which is inherently prone to cumulative errors. Some chariots mechanisms may have had differential gears, if so, it was probably the first use of differentials anywhere in the world. The south-pointing chariot, a wheeled vehicle used to discern the southern cardinal direction, was given a brief description by Mas contemporary Fu Xuan. The contemporary 3rd century CE source of the Weilüe, written by Yuan Huan also described the south-pointing chariot of Ma Jun, the book also provided description of the south-pointing chariots re-invention and use in times after Ma Jun and the Three Kingdoms. The 6th century CE text reads as follows, (In this translation, by Needham, the south-pointing chariot is referred to as the south-pointing carriage. The last sentence of the passage is of great interest for navigation at sea, in fact, the first known source to describe stories of its legendary use during the Zhou period was the Gu Jin Zhu book of Cui Bao, written soon after the Three Kingdoms era. Cui Bao also wrote that the details of construction for the device were once written in the Shang Fang Gu Shi. The invention of the chariot also made its way to Japan by the 7th century. The Nihon Shoki of 720 CE described the earlier Chinese Buddhist monks Zhi Yu and this was followed up by several more chariot devices built in 666 CE as well. The south-pointing chariot was combined with the earlier Han Dynasty era invention of the odometer, a mechanical device used to measure distance traveled. It was mentioned in the Song Dynasty historical text of the Song Shi that the engineers Yan Su, a differential is an assembly of gears, nowadays used in almost all automobiles except some electric and hybrid-electric ones, which has three shafts linking it to the external world. They are conveniently labelled A, B, and C, the gears cause the rotation speed of Shaft A to be proportional to the sum of the rotation speeds of Shafts B and C. There are no limitations on the rotation speeds of the shafts

Middle Ages
–
In the history of Europe, the Middle Ages or Medieval Period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance, the Middle Ages is the middle period of the three traditional divisions of Western history, classical antiquity, the medieval period, and the modern period. The medieval period is subdivided into the Early, High. Population decline, counterurbanisation, invasion, and movement of peoples, the large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the seventh century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, although there were substantial changes in society and political structures, the break with classical antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power, the empires law code, the Corpus Juris Civilis or Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions, monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th, the Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from Muslims. Kings became the heads of centralised nation states, reducing crime and violence, intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. Controversy, heresy, and the Western Schism within the Catholic Church paralleled the conflict, civil strife. Cultural and technological developments transformed European society, concluding the Late Middle Ages, the Middle Ages is one of the three major periods in the most enduring scheme for analysing European history, classical civilisation, or Antiquity, the Middle Ages, and the Modern Period. Medieval writers divided history into periods such as the Six Ages or the Four Empires, when referring to their own times, they spoke of them as being modern. In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua, leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People. Bruni and later argued that Italy had recovered since Petrarchs time. The Middle Ages first appears in Latin in 1469 as media tempestas or middle season, in early usage, there were many variants, including medium aevum, or middle age, first recorded in 1604, and media saecula, or middle ages, first recorded in 1625. The alternative term medieval derives from medium aevum, tripartite periodisation became standard after the German 17th-century historian Christoph Cellarius divided history into three periods, Ancient, Medieval, and Modern. The most commonly given starting point for the Middle Ages is 476, for Europe as a whole,1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period

Hussite Wars
–
These wars lasted from 1419 to approximately 1434. The Hussite community included most of the Czech population of the Kingdom of Bohemia and they defeated five crusades proclaimed against them by the Pope, and intervened in the wars of neighboring countries. The Hussite Wars were notable for the use of early hand-held firearms such as hand cannons. The fighting ended after 1434, when the moderate Utraquist faction of the Hussites defeated the radical Taborite faction, the Hussites agreed to submit to the authority of the King of Bohemia and the Church, and were allowed to practice their somewhat variant rite. Starting around 1402, priest and scholar Jan Hus denounced what he judged as the corruption of the Church and the Papacy and his preaching was widely heeded in Bohemia, and provoked suppression by the Church, which had declared Wycliffe a heretic. In 1411, in the course of the Western Schism, Antipope John XXIII proclaimed a crusade against King Ladislaus of Naples, to raise money for this, he proclaimed indulgences in Bohemia. Hus bitterly denounced this and explicitly quoted Wycliffe against it, provoking further complaints of heresy, in 1414, Sigismund of Hungary convened the Council of Constance to end the Schism and resolve other religious controversies. Hus went to the Council, under a safe-conduct from Sigismund, but was imprisoned, tried and this angered Sigismund, who was King of the Romans, and brother of King Wenceslaus of Bohemia. He had been persuaded by the Council that Hus was a heretic and he sent threatening letters to Bohemia declaring that he would shortly drown all Wycliffites and Hussites, greatly incensing the people. Disorder broke out in parts of Bohemia, and drove many Catholic priests from their parishes. Almost from the beginning the Hussites divided into two groups, though many minor divisions also arose among them. This doctrine became the watchword of the moderate Hussites known as the Utraquists or Calixtines, from the Latin calix, in Czech kališníci. The more extreme Hussites became known as Taborites, after the city of Tábor that became their center, or Orphans, under the influence of Sigismund, Wenceslaus endeavoured to stem the Hussite movement. A number of Hussites led by Mikuláš of Hus — no relation of Jan Hus — left Prague and they held meetings in various parts of Bohemia, particularly at Sezimovo Ústí, near the spot where the town of Tábor was founded soon afterwards. At these meetings they violently denounced Sigismund, and the people prepared for war. In spite of the departure of many prominent Hussites, the troubles at Prague continued and it has been suggested that Wenceslaus was so stunned by the defenestration that it caused his death on 16 August 1419. The death of Wenceslaus resulted in renewed troubles in Prague and in almost all parts of Bohemia, many Catholics, mostly Germans — mostly still faithful to the Pope — were expelled from the Bohemian cities. Wenceslaus widow Sophia of Bavaria, acting as regent in Bohemia, hurriedly collected a force of mercenaries and tried to control of Prague

Bohemia
–
Bohemia is the westernmost and largest historical region of the Czech lands in the present-day Czech Republic. Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg Monarchy, after World War I and the establishment of an independent Czechoslovak state, Bohemia became a part of Czechoslovakia. Between 1938 and 1945, border regions with sizeable German-speaking minorities of all three Czech lands were joined to Nazi Germany as the Sudetenland, in 1990, the name was changed to the Czech Republic, which become a separate state in 1993 with the dissolution of Czechoslovakia. Until 1948, Bohemia was a unit of Czechoslovakia as one of its lands. Bohemia was bordered in the south by Upper and Lower Austria, in the west by Bavaria and in the north by Saxony and Lusatia, in the northeast by Silesia, and in the east by Moravia. In the 2nd century BC, the Romans were competing for dominance in northern Italy, the Romans defeated the Boii at the Battle of Placentia and the Battle of Mutina. After this, many of the Boii retreated north across the Alps, much later Roman authors refer to the area they had once occupied as Boiohaemum. The earliest mention was by Tacitus Germania 28, and later mentions of the name are in Strabo. The name appears to include the tribal name Boi- plus the Germanic element *haimaz home and this Boiohaemum was apparently isolated to the area where King Marobods kingdom was centred, within the Hercynian forest. The Czech name Čechy is derived from the name of the Slavic ethnic group, the Czechs, Bohemia, like neighbouring Bavaria, is named after the Boii, who were a large Celtic nation known to the Romans for their migrations and settlement in northern Italy and other places. Another part of the nation moved west with the Helvetii into southern France, to the south, over the Danube, the Romans extended their empire, and to the southeast in Hungaria, were Sarmatian peoples. In the area of modern Bohemia the Marcomanni and other Suebic groups were led by their king Marobodus and he took advantage of the natural defenses provided by its mountains and forests. In late classical times and the early Middle Ages, two new Suebic groupings appeared to the west of Bohemia in southern Germany, the Alemanni, many Suebic tribes from the Bohemian region took part in such movements westwards, even settling as far away as Spain and Portugal. With them were also tribes who had pushed from the east, such as the Vandals, other groups pushed southwards towards Pannonia. These are precursors of todays Czechs, though the amount of Slavic immigration is a subject of debate. The Slavic influx was divided into two or three waves, the first wave came from the southeast and east, when the Germanic Lombards left Bohemia. Soon after, from the 630s to 660s, the territory was taken by Samos tribal confederation and his death marked the end of the old Slavonic confederation, the second attempt to establish such a Slavonic union after Carantania in Carinthia. Other sources divide the population of Bohemia at this time into the Merehani, Marharaii, Beheimare, Christianity first appeared in the early 9th century, but only became dominant much later, in the 10th or 11th century

Infantry
–
Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare, Infantry can enter and maneuver in terrain that is inaccessible to military vehicles and employ crew-served infantry weapons that provide greater and more sustained firepower. In English, the 16th-century term Infantry describes soldiers who walk to the battlefield, and there engage, fight, the term arose in Sixteenth-Century Spain, which boasted one of the first professional standing armies seen in Europe since the days of Rome. It was common to appoint royal princes to military commands, and the men under them became known as Infanteria. in the Canadian Army, the role of the infantry is to close with, and destroy the enemy. In the U. S. Army, the closes with the enemy, by means of fire and maneuver, in order to destroy or capture him, or to repel his assault by fire, close combat. In the U. S. Marine Corps, the role of the infantry is to locate, close with, and destroy the enemy fire and maneuver. Beginning with the Napoleonic Wars of the early 19th century, artillery has become a dominant force on the battlefield. Since World War I, combat aircraft and armoured vehicles have become dominant. In 20th and 21st century warfare, infantry functions most effectively as part of a combined arms team including artillery, armour, Infantry relies on organized formations to be employed in battle. These have evolved over time, but remain a key element to effective infantry development and deployment, until the end of the 19th century, infantry units were for the most part employed in close formations up until contact with the enemy. This allowed commanders to control of the unit, especially while maneuvering. The development of guns and other weapons with increased firepower forced infantry units to disperse in order to make them less vulnerable to such weapons. This decentralization of command was made possible by improved communications equipment, among the various subtypes of infantry is Medium infantry. This refers to infantry which are heavily armed and armored than heavy infantry. In the early period, medium infantry were largely eliminated due to discontinued use of body armour up until the 20th century. In the United States Army, Stryker Infantry is considered Medium Infantry, since they are heavier than light infantry, Infantry doctrine is the concise expression of how infantry forces contribute to campaigns, major operations, battles, and engagements. It is a guide to action, not a set of hard, doctrine provides a very common frame of reference across the military forces, allowing the infantry to function cooperatively in what are now called combined arms operations. Doctrine helps standardise operations, facilitating readiness by establishing common ways of accomplishing infantry tasks, doctrine links theory, history, experimentation, and practice

Holy Roman Empire
–
The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as Emperor, reviving the title in Western Europe, more than three centuries after the fall of the Western Roman Empire. The title was revived in 962 when Otto I was crowned emperor, fashioning himself as the successor of Charlemagne, some historians refer to the coronation of Charlemagne as the origin of the empire, while others prefer the coronation of Otto I as its beginning. Scholars generally concur, however, in relating an evolution of the institutions and principles constituting the empire, the office of Holy Roman Emperor was traditionally elective, although frequently controlled by dynasties. Emperor Francis II dissolved the empire on 6 August 1806, after the creation of the Confederation of the Rhine by Napoleon, before 1157, the realm was merely referred to as the Roman Empire. In a decree following the 1512 Diet of Cologne, the name was changed to Holy Roman Empire of the German Nation, by the end of the 18th century, the term Holy Roman Empire of the German Nation had fallen out of official use. As Roman power in Gaul declined during the 5th century, local Germanic tribes assumed control, by the middle of the 8th century, however, the Merovingians had been reduced to figureheads, and the Carolingians, led by Charles Martel, had become the de facto rulers. In 751, Martel’s son Pepin became King of the Franks, the Carolingians would maintain a close alliance with the Papacy. In 768 Pepin’s son Charlemagne became King of the Franks and began an expansion of the realm. He eventually incorporated the territories of present-day France, Germany, northern Italy, on Christmas Day of 800, Pope Leo III crowned Charlemagne emperor, restoring the title in the west for the first time in over three centuries. After the death of Charles the Fat in 888, however, the Carolingian Empire broke apart, according to Regino of Prüm, the parts of the realm spewed forth kinglets, and each part elected a kinglet from its own bowels. After the death of Charles the Fat, those crowned emperor by the pope controlled only territories in Italy, the last such emperor was Berengar I of Italy, who died in 924. Around 900, autonomous stem duchies reemerged in East Francia, on his deathbed, Conrad yielded the crown to his main rival, Henry the Fowler of Saxony, who was elected king at the Diet of Fritzlar in 919. Henry reached a truce with the raiding Magyars, and in 933 he won a first victory against them in the Battle of Riade, Henry died in 936, but his descendants, the Liudolfing dynasty, would continue to rule the Eastern kingdom for roughly a century. Upon Henry the Fowlers death, Otto, his son and designated successor, was elected King in Aachen in 936 and he overcame a series of revolts from an elder brother and from several dukes. After that, the managed to control the appointment of dukes. In 951, Otto came to the aid of Adelaide, the queen of Italy, defeating her enemies, marrying her. In 955, Otto won a victory over the Magyars in the Battle of Lechfeld

Landsknecht
–
Consisting predominantly of German mercenary pikemen and supporting foot soldiers, they achieved the reputation for being the universal mercenaries of early modern Europe. The Germanic compound Landsknecht combines land land, country, here in the sense of lowlands and knecht servant, vassal, the compound Lantknecht was used during the 15th century of bailiffs or court ushers. As early as 1500, the term was re-etymologized as Lanzknecht, suggesting a derivation from Lanze lance, the modern term Landser is possibly based on Landsknecht, as is the name of the French card game Lansquenet. The more common English-language plural form is Landsknechts, but the original German form Landsknechte is also in use, since it is a common noun, it may also be written with lower-case l, landsknechts. Maximilian I, Holy Roman Emperor from 1493 to 1519, formed the first mercenary Landsknecht regiments in 1487 and he called upon Georg von Frundsberg, sometimes referred to as the Father of the Landsknechts, to assist him in their organization. Landsknechts later went on to fight in almost every 16th-century military campaign, French artillery or Spanish firepower dealt serious blows to the Swiss formations, and the Landsknecht pike blocks were there to fight off the depleted Swiss attack columns once this had occurred. The Landsknechts were conservative in their usage of weapons and contained a majority of pikemen. However, they inclined more to the use of firearms than the Swiss because Landsknechts relied less on the precipitous rush to close combat. As Imperial soldiers, they fought in formations mixed with Spaniards during the reign of King of Spain. These Spaniards made a widespread use of the arquebus and later. Landsknechte typically came from Swabia, Alsace, Tyrol and the Rhineland, in the 1490s, the well-trained Landsknechte managed to defeat significantly greater Frisian armies. Paul Dolstein wrote of the siege of Älfsborg in July 1502, fighting for the King of Denmark, We were 1800 Germans and we struck most of them dead. In 1521, the Spaniards recruited German infantrymen to defend their country against the French because, at the Battle of Bicocca and the Battle of Marignano, they performed well, defeating the famed Swiss Pikemen. The Imperial Landsknechts were instrumental in many of the Emperors victories, the same year, they also managed to defeat the peasants revolt in the Empire. At their peak in the early 16th century, the Landsknechte were considered as formidable soldiers who were often brave, however, these qualities may have declined afterward. Indeed, from the 1560s on, the reputation of the Landsknechte steadily decreased and their status also suffered from the rising reputation of the dreaded Spanish tercios which, however, were far less abundant and more expensive to train. It should also be noted that when serving in southern Europe, in the army of the Dutch rebels, many German mercenaries were hired but were forced to give up many Landsknechtes traditions in order to increase their discipline and their fighting abilities. They are attested as deployed in the armies of Kings John III of Navarre, in the same context, they are found fighting on Charles Vs side too where they performed strongly

Fire arrow
–
Fire arrows are one of the earliest forms of weaponized gunpowder. The first fire arrows were bags of gunpowder attached the shaft of an arrow. Later on gunpowder rockets were used to provide rockets with propulsive force, fire arrows are the predecessors of fire lances, the first firearm. Although the fire arrow is most commonly associated with its rocket mechanism and this type of fire arrow served the function of an incendiary and was launched using a bow or crossbow. The rocket propelled fire arrow appeared later, by the mid 1300s rocket arrow launchers had appeared in the Ming dynasty and later on mobile rocket arrow launchers were utilized in both China and Korea. The fire arrows propelled by gunpowder may have had a range of up to 1,000 feet, fire arrows were first reported to be used by the Southern Wu in 904 during the siege of Yuzhang. In 969 gunpowder propelled rocket arrows were invented by Yue Yifang and Feng Jisheng, in 1083 Song records state that the court produced 350,000 fire arrows and sent them to two garrisons. On March 1,1126, the Song general Li Gang used a fire arrow machine known as the Thunderbolt Thrower during the Jingkang Incident, by 1127 the Jin were also using fire arrows produced by captured Song artisans. In 1159 fire arrows were used by the Song navy in sinking a Jin fleet, in 1161 the general Yu Yunwen used fire arrows at the Battle of Caishi, near present-day Maanshan, during a Jin maritime incursion. The Mongols also made use of the fire arrow during their campaigns in Japan, as a result of the Mongolian military campaigns the fire arrow later spread into the Middle East. In 1374 the kingdom of Joseon also started producing gunpowder and by 1377 were producing fire arrows and cannons, korean fire arrows were used against the Japanese during the invasion of Korea. In 1380 an order of wasp nest arrow rocket launchers were ordered by the Ming army, in 1451 a type of mobile arrow rocket launcher known as the Munjong Hwacha was invented in Joseon. The Japanese version of the fire arrow were known as bo-hiya, Japanese pirates in the 16th century were reported to have used bo hiya. During one sea battle it was said the bo-hiya were falling like rain, andrade, Tonio, The Gunpowder Age, China, Military Innovation, and the Rise of the West in World History, Princeton University Press, ISBN 978-0-691-13597-7.

Armored car (military)
–
A military armored car is a lightweight wheeled armored fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties formerly assigned to horsemen, following the invention of the tank, the armored car remained popular due to its comparatively simplified maintenance and low production cost. It also found favor with several colonial armies as a weapon for use in underdeveloped regions. During World War II, most armored cars were engineered for reconnaissance and passive observation, some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African Campaign. The Motor Scout was designed and built by British inventor F. R. Simms in 1898 and it was the first armed petrol engine-powered vehicle ever built. The vehicle was a De Dion-Bouton quadricycle with a mounted Maxim machine gun on the front bar, an iron shield in front of the car protected the driver. However, these were not armored cars as the term is understood today and they were also, by virtue of their small capacity engines, less efficient than the cavalry and horse-drawn guns that they were intended to complement. At the beginning of the 20th century, the first military armored vehicles were manufactured, by adding armor and weapons to existing vehicles. The vehicle had Vickers armour 6 mm thick and was powered by a four-cylinder 3. 3-litre 16-hp Cannstatt Daimler engine, the armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. Simms Motor War Car was presented at the Crystal Palace, London, another early armored car of the period was the French Charron, Girardot et Voigt 1902, presented at the Salon de lAutomobile et du cycle in Brussels, on 8 March 1902. The vehicle was equipped with a Hotchkiss machine gun, and with 7 mm armour for the gunner, one of the first operational armoured cars with four wheel drive and fully enclosed rotating turret, was the Austro-Daimler Panzerwagen built by Austro-Daimler in 1904. It was armoured with 3-3.5 mm thick curved plates over the body and had a 4mm thick dome-shaped rotating turret that housed one or two machine-guns and it had a 4-cylinder 35 hp 4.4 litre engine giving it average cross country performance. Of note, both the driver and co-driver had adjustable seats enabling them to them to see out of the roof of the drive compartment as needed. The Italians used armored cars during the Italo-Turkish War, a great variety of armored cars appeared on both sides during World War I and these were used in various ways. Generally, the cars were used by more or less independent car commanders. However, sometimes they were used in units up to squadron size. The cars were armed with light machine guns, but larger units usually employed a few cars with heavier guns. As air power became a factor, armored cars offered a platform for antiaircraft guns

Armoured personnel carrier
–
An armoured personnel carrier is a type of armoured fighting vehicle designed to transport infantry to the battlefield. APCs are colloquially referred to as taxis or battle buses. Armoured personnel carriers are distinguished from infantry fighting vehicles by the weaponry they carry, by convention, they are not intended to take part in direct-fire battle, but are armed for self-defence and armoured to provide protection from shrapnel and small arms fire. Examples include the American M113, the French VAB, the Dutch-German GTK Boxer, the genesis of the armoured personnel carrier was on the Western Front of World War I. In the later stage of the war, Allied tanks could break through enemy lines, without infantry support, the tanks were isolated and more easily destroyed. In response, the British experimented with carrying machine-gun crews in the Mark V* tank, britain therefore designed the first purpose built armoured troop transport, the Mark IX, but the war ended before it could be put to use. During World War II, half-tracks like the American M3 and German SdKfz 251 played a similar to post-war APCs. British Commonwealth forces relied on the full-tracked Universal Carrier, over the course of the war, APCs evolved from simple armoured cars with transport capacity, to purpose built vehicles. Obsolete armoured vehicles were also repurposed as APCs, such as the various Kangaroos converted from M7 Priest self-propelled guns and from Churchill, M3 Stuart, during the Cold War, more specialized APCs were developed. Western nations have since retired most M113s, replacing them with newer APCs, the Soviet Union produced the BTR-40, BTR-152, BTR-60, BTR-70, BTR-80 in large numbers. The BTR-60 and BTR-80 remain in production, czechoslovakia and Poland together developed the universal amphibious OT-64 SKOT. A cold war example of a Kangaroo is the heavily armoured Israeli Achzarit, weight can vary from 6 to 40 tons or more, but 9 to 20 tons is typical. Most have a capacity of between 8 and 12 dismountable troops, although some can carry more than 20, in addition, it has a crew of at least one driver, many with a gunner and/or commander as well. An APC is either wheeled or tracked, or occasionally a combination of the two, as in a half-track, both systems have advantages and limitations. Tracked vehicles have more traction off-road and more maneuverability, including a turn radius. Wheeled APCs are faster on road, can cross long distances, and are expensive to develop, produce. However, wheeled vehicles have higher pressure than tracked vehicles with a comparable weight. The higher ground pressure increases the likelihood of becoming immobilized by soft terrains such as mud and their tracks can propel the APC in the water

Wagon fort
–
A wagon fort is a mobile fortification made of wagons arranged into a rectangle, a circle or other shape and possibly joined with each other, an improvised military camp. It is also known as a laager, ammianus Marcellinus, a Roman army officer and historian of the 4th century, describes a Roman army approaching ad carraginem as they approach a Gothic camp. Historians interpret this as a wagon-fort, similar ad hoc defense formations were used in the United States, and were called corrals. These were traditionally used by 19th century American settlers travelling to the West in convoys of Conestoga wagons. The armed men would then man the perimeter, the circled wagons serving to break up the charge, to create a certain amount of concealment from observation. This tactic was known as circling up the wagons. One of the earliest examples of using conjoined wagons as fortification is described in the Chinese historical record Book of Han, in the 13th century, the armies of Kievan Rus used tabors in the Battle of Kalka to defend themselves from Mongol forces. In the 15th century, during the Hussite Wars, the Hussites developed tactics of using the tabors, called vozová hradba in Czech or Wagenburg by the Germans, such a camp was easy to establish and practically invulnerable to enemy cavalry. The etymology of the word tabor may come from the Hussite fortress and modern day Czech city of Tábor, which itself is a name derived from biblical Jezreel mountain Tavor. The crew of each wagon consisted of 18 to 21 soldiers,4 to 8 crossbowmen,2 handgunners,6 to 8 soldiers equipped with pikes or flails,2 shield carriers and 2 drivers. The wagons would normally form a square, and inside the square would usually be the cavalry, there were two principal stages of the battle using the wagon fort, defensive and counterattack. The defensive part would be a pounding of the enemy with artillery, the Hussite artillery was a primitive form of a howitzer, called in Czech a houfnice, from which the English word howitzer comes. Also, they called their guns the Czech word píšťala, meaning that they were shaped like a pipe or a fife, from which the English word pistol is possibly derived. When the enemy would come close to the fort, crossbowmen and hand-gunners would come from inside the wagons. There would even be stored in a pouch inside the wagons for throwing whenever the soldiers were out of ammunition. After this huge barrage, the enemy would be demoralized, once the commander saw it fit, the second stage of battle would begin. Men with swords, flails, and polearms would come out, together with the infantry, the cavalry in the square would come out and attack. At this point, the enemy would be eliminated or very nearly so, the wagon forts effect on Czech history was lost, but the Czechs would continue to use the wagon forts in later conflicts

Tank
–
A tank is an armoured fighting vehicle designed for front-line combat, with heavy firepower, strong armour, and tracks providing good battlefield maneuverability. The first tanks were designed to overcome the deadlock of trench warfare, now they are a mainstay of ground forces. Modern tanks are versatile mobile land weapon platforms, mounting a large-calibre cannon in a rotating gun turret. In both offensive and defensive roles, they are units that are capable of performing tasks which are required of armoured units on the battlefield. As a result of advances, tanks underwent tremendous shifts in capability in the years since their first appearance. Tanks in World War I were developed separately and simultaneously by Great Britain and this was a prototype of a new design that would become the British Armys Mark I tank, the first tank used in combat in September 1916 during the Battle of the Somme. The name tank was adopted by the British during the stages of their development. While the British and French built thousands of tanks in World War I, Germany was unconvinced of the tanks potential, Tanks of the interwar period evolved into the much larger and more powerful designs of World War II. Tanks in the Cold War were designed with these weapons in mind, improved engines, transmissions and suspensions allowed tanks of this period to grow larger. Aspects of gun technology changed significantly as well, with advances in shell design, during the Cold War, the main battle tank concept arose and became a key component of modern armies. Modern tanks seldom operate alone, as they are organized into combined arms units which involve the support of infantry and they are also usually supported by reconnaissance or ground-attack aircraft. The tank is the 20th century realization of an ancient concept, the internal combustion engine, armour plate, and continuous track were key innovations leading to the invention of the modern tank. Many sources imply that Leonardo da Vinci and H. G. Wells in some way foresaw or invented the tank, leonardos late 15th century drawings of what some describe as a tank show a man-powered, wheeled vehicle with cannons all around it. However the human crew would not have power to move it over larger distance. In the 15th century, Jan Žižka built armoured wagons containing cannons, the caterpillar track arose from attempts to improve the mobility of wheeled vehicles by spreading their weight, reducing ground pressure, and increasing their traction. Experiments can be traced back as far as the 17th century and it is frequently claimed that Richard Lovell Edgeworth created a caterpillar track. It is true that in 1770 he patented a machine, that should carry and lay down its own road and his own account in his autobiography is of a horse-drawn wooden carriage on eight retractable legs, capable of lifting itself over high walls. The description bears no similarity to a caterpillar track, armoured trains appeared in the mid-19th century, and various armoured steam and petrol-engined vehicles were also proposed

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker
